when the Output Cam is terminated by a Motion Disarm Output Cam (MDOC)
instruction.

Motion Alarm Bits and Motion Fault Bits Descriptions
Bit Name Description
0 Reserved -
1 SoftTravelLimitPositiveAlarm
SoftTravelLimitPositiveFault
This exception condition occurs when Soft Travel Checking is
enabled and when actual position has exceeded the configured Soft
Travel Limit - Positive attribute value while commanding motion in
the positive direction.
If the Motion Exception Action for this bit is set for Stop Planner, the
faulted axis can be moved or jogged back inside the soft travel
limits. Any attempt, however, to move the axis further beyond the
Soft Travel Limit - Positive value using a motion instruction will
result in an instruction error.
For commanded axes, the Soft Travel Fault can be cleared with a
Fault Reset while the axis position is beyond the Soft Travel Limit -
Positive value to allow the axis to be moved back within the Soft
Travel Limits. As long as the axis is not commanded to move further
away from the travel limit, no Soft Travel Limit Fault shall be
generated.
